Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 7; Anale zachte stralen: 12 - 13; Wervels: 49 - 50. The following characters distinguished this species from all members of the Hemibagrus planiceps species group: dorsal to adipose distance 7.6-10.9% SL (vs. 10.6-17.6); adpressed dorsal fin reaching (vs. not reaching the origin of the adipose fin) and (except for H. bongan and H. planiceps) adipose-fin base 18.8-20.4% SL (vs. 11.1-17.9). Can be further distinguished from H. bongan in having body depth at anus 12.2-13.6% SL (vs. 9.5-12.9), and from H. divaricatus in having maximum height of adipose fin 4.1-6.0 times in length of base (vs. 1.9-3.2) and eye diameter 17-19% HL (vs. 11-17). Differs further differs from H. gracilis in having caudal peduncle depth 7.3-8.1% SL (vs. 6.2-7.6) and vertebrae 49-50 (vs. 50-52) and H. planiceps in having interorbital distance 30-32% HL (vs. 32-37) and vertebrae 49-50 (vs. 47-49) (Ref. 93057).
The upper Ombilin River where this species occupies is relatively swift flowing, with a substrate of gravel and rock. Believed to inhabit inshore areas of the lake, Danau Singkarak. Sympatric with Hemibagrus velox (Ref. 93057).
